Enables Ability to Run Multiple Versions of an Oracle Database Simultaneously May 18, 2012,
Volume 171, Issue 3
In a lengthy how-to on deploying Oracle RAC on zone clusters Vinh Tran provides the code samples for the procedure and the screen shots that illustrate it. Tranh explains that by installing Oracle RAC inside a zone cluster, you can run multiple instances of an Oracle database at the same time, allowing you to have separate database versions or separate deployments of the same database (for example, one for production and one for development). This architecture enables the deployment of different parts of a multitiered solution into different virtual zone clusters, in turn allowing users to isolate tiers and administrative domains from each other, while taking advantage of the simplified administration provided by Oracle Solaris Cluster.
